In our ecologically concerned world, the growing demand for energy to support human needs presents an increasing issue. The current primary energy source’s heavy reliance on fossil fuels not only depletes limited resources but also greatly increases environmental pollution. The solution to this conundrum is a radical move in the direction of sustainable alternatives, of which solar energy is a prime contender because it produces no pollution. It is essential to switch completely to solar energy from conventional energy sources in order to ensure a cleaner and greener future. However, the investigation and implementation of novel systems that smoothly combine solar energy harvesting and storage into a single apparatus. Remarkably, the integration of solar energy conversion and storage systems is still undergoing significant advancements, as the scientific community has recently embarked on exploring this subject. This study investigates a pressing need in modern times: the development of a singular gadget known as “photo-supercapacitors”. The performance and efficiency of the system are thoroughly examined by assessing the crucial factors. The paper provides a thorough overview of the progress made in enhancing the flexibility and efficiency of photo-supercapacitors, offering valuable insights into the promising future of energy systems and technology.
